Abstract: A pipe bracket for use in a freight brake control valve on a railway freight vehicle.  A service portion and an emergency portion are mounted to a first pipe bracket side directed opposite to the first pipe bracket side.  Piping to a brake pipe, a brake cylinder, an emergency reservoir and an auxiliary reservoir are connected to a second side of the pipe bracket.  A plurality of passageways are provided through the pipe bracket portion for providing fluid communication from the brake pipe, the brake cylinder, the emergency reservoir, and the auxiliary reservoir to the service portion and the emergency portion.  One or more and preferably four access ports connect to one or more and preferably each of the passageways.          Preferably, the access ports are provided on the first side of the pipe bracket portion.  A housing having one or more channels, each corresponding to an access port is engaged to the pipe bracket portion so that fluid pressure at the access ports can be transmitted to the housing.

Abstract: The present invention provides a glass sheet shaping arrangement whereby a glass sheet may be conveyed through a shaping station without being shaped and deposited into a glass collector beneath an upstream portion of the adjacent quench without impacting the lower quench or interfering with the operation of the quench. A furnace, shaping station and cooling station are all linearly aligned so that a glass sheet progresses through the glass sheet shaping arrangement without changing its advancing direction. A glass sheet is conveyed in a first direction along a first generally horizontal plane through the furnace to heat the sheet to its heat softening temperature. The sheet continues into the shaping station where it is lifted into engagement with an upper vacuum surface. A ring member moves along a second generally horizontal plane in a direction which is linearly aligned with the first direction, from a first position between an upper and lower quench in the cooling station to a second position within the shaping station beneath the upper vacuum surface. Vacuum is terminated along the upper surface, depositing the sheet on the ring. The shaped sheet is cooled by moving the ring from the second position within the shaping station along the second plane to the first position within the cooling station. The second plane is vertically offset relative to the first plane such that the first planeis beneath a portion of the lower quench which is immediately adjacent the shaping station. With this arrangement, the glass sheets may be conveyed through the shaping station and into the collector without interfering with any further production.

Abstract: A method and system for aggregating objects within a computer system are provided. In a preferred embodiment, the method aggregates an enclosed object within an enclosing object. The enclosed object has an object management interface and an external interface, while the enclosing object has a controlling object management interface. The controlling object management interface and the external interface of the enclosed object have query function members for receiving an identifier of an interface and for returning a reference to the identified interface. A preferred embodiment creates an instance of an enclosing object and an object to be enclosed. In static aggregation, the controlling object management interface of the enclosing object knows in advance how to return an identifier to the external interface of the enclosed object. In dynamic aggregation, an object to be enclosed is added to the enclosing object after the enclosing object is instantiated. Once aggregated, when the query function member of the object management interface of the enclosed object receives an identifier of an interface, it invokes the query function member of the controlling object management interface forwarding the interface identifier and returns the reference to an interface returned by the invoked query function member of the controlling object management interface. In dynamic aggregation, rules for determining to which interface to return a reference can by added to the enclosing object and used by the query function member of the controlling object management interface.

Title: Process for clarifying milkhouse wastewater
Inventor: MALCOLM IAN
IPC: C02F1/52
Filed: 1995-03-31
Granted: 2001-11-06
Abstract: A process and apparatus are described for clarifying milkhouse wastewater, which is rich in phosphorous and also contains colloïdal and suspended solids.  This wastewater is obtained during the washing of milk pipelines of a diary milking system. The wastewater is collected in a treatment vessel, with the ratio of suspended solids to phosphorus in the wastewater being lowered either before entering or while in the treatment vessel. To this wastewater of lowered suspended solids:phosphorus ratio, there is added sufficient calcium, preferably in the form of lime, to react with all of the phosphorus in the wastewater to form calcium hydroxyapatite precipitate. It has been discovered that, by lowering the ratio of suspended solids:phosphorus, sufficient calcium hydroxyapatite precipitate is formed to sweep with it during settling substantially all colloïdal and suspended solids thereby leaving a clear, environmentally safe effluent water. The ratio of suspended solids:phosphorus is easily lowered by initially flushing the system with a small quantity of water and separately collecting this initial flush water having a high concentration of suspended solids.

Title: Method and arrangement for establishing call connections in a telecommunications network using a virtual transport server
Inventor: BORCHERING JAMES WILLIAM
IPC: H04M7/00
Filed: 1996-12-17
Granted: 2001-02-20
Abstract: A telecommunications network comprises a virtual transport server (VTS) for making network routing decisions and establishing call connections. Each VTS is interconnected to each signal transfer point in a common channel signaling (CCS)system associated with the network. Each VTS is also interconnected to at least one switch in a transmission network, such as an asynchronous transfer mode (ATM) switch. The VTS maintains routing tables identifying trunk groups associated with each central office switch in the network. During operation, an initial address message received from a signal transfer point in the VTS is processed and subsequently extended to an ATM switch so that a call connection can be established. Upon completion of the established call, the VTS releases resources associated with the ATM switch.
